[qa] Net.py fails occasionally #11778

   In net.py we compare the exact number of bytes transmitted or received of two subsequently called rpcs. This fails occasionally. I hypothesise that this might be caused by cross-traffic that happens in between those rpcs, which are obviously not called atomically.

   If that is the case, we might be able to repeat the calls up to ${n} times and hope that cross-traffic does not happen in all ${n} cases.

   Relevant example log:

   Agree that your hypothesis is the most likely explanation here.

   Your fix seems reasonable. Will open a PR.
